Dome Homes Made from Inflatable Concrete Cost Just $3,500

Binishells may be the greenest way to build ever invented. Using air as their form work, Binishells are inherently green because they provide highly efficient building envelopes. They are also naturally strong and flexible in terms of shape and size. They are highly affordable because they use less labor and material in construction and also because they cost less to operate.

Inflatable concrete homes, sounds like something from a science-fiction movie when in fact it is reality. Inflatable concrete, is a material created with the use of new technology and these next dome homes below resemble houses from an ancient time. The concrete Binishell dome homes are a creation of architect Nicolo Bini and the technique he used is very strange, but innovating.

He starts from ground level and slowly builds the layers of the walls, then adds a load of concrete to create the domes. This technique forms the concrete with the help of an air bladder that is deflated when the final form of the building is reached

More than 1,600 Binishells System domes have been built in 23 countries. That's more domes built in this way than with any other construction system in history. Invented in 1964 by Dr. Dante Bini, this innovative system was the first to utilize air pressure to lift and shape reinforced concrete shell structures poured at ground level.

Domes of up to 40m (120ft.) have been raised in less than one hour using less than 1 PSI of pressure. Applications have ranged from high end homes, to schools, silos, military facilities, sports facilities and a wide variety of purposes.
